Test
& Alignment
According to the requirement of order, we suggest take the below steps to
finish the appropriate settings.
Note:
All tests and measurements mentioned hereafter have to be carried out at a
normal mains voltage (100 ~ 240 VAC)
All voltages have to be measured with respect to ground, unless otherwise
stated
All
final tests have to be done on a complete set including LCD panel in a room
with temperature of 25+/-7°C.
The
Picture Performance assessment such as White Balance (luminance and colour
temperature) has to be performed into subdued lighted room after at least 60min
of warm-up in order to avoid any temperature drift influence (colorimetry vs
time).
Pre-Conditions and Power Supply Check
Before power-on, please check the board according to the relevant block diagram
and circuit diagram, make sure that no serious issue or mistake can destroy the
board. For example, the output of DC/DC and LDO should not be shorted to
ground.
Supply a suited voltage and power-on, then check the voltage according to the
relevant block diagram, circuit diagram and voltage spec, the error should be
less than 5%, for example, the voltage for main chip (+3V3, +2.5V, VDDC1V15,
1V5_DDR, etc.), the voltage for TUNER (TU_3V3), the voltage for amplifier (AMP_VCC),
etc.
Project ID Modification
There are different ID stored in the EMMC depending on different Panels
settings and Model features, but there’s only one key branching Project ID able
to ensure normal display. And when you power on the TV set, you should make
sure the Project ID is accord with the BOM description. If not, you need to
modify the ID. There are two methods to modify the ID:
Change Project ID in Design Menu
In case of “Design mode hotkey” is enabled, press “Back” button to enter Design
Menu. To modify Project ID, you need to go through “Service menuàProject ID”, then press Left or Right
key to select suitable ID (Project name is dynamically refreshed). Finally
restart the TV set.
In case of “Design mode hotkey” is unabled, you can enter the Design Menu
easily with reference to Design Menu.
Change Project ID with RCU
Press “062598”+”Menu”+”XXX” (XXX represents project ID you’d like to switch to)
in the remote control and wait about half minutes, When the set restart
automatically, you have successfully changed project ID. below is none
exhaustive ProjectID table for reference.
Function Test
Once the Project ID is correct and the TV display normally, plug all external
generator devices to relevant inputs/outputs according to their respective test
patterns format and check picture content and sound quality accordingly.
LAN/WLAN
Test
MAC Address Upgrade
Upgrading MAC address needs to use the tool in factory and through serial
command. The specific method is according to the operation of the factory
guidance.
DeviceID (DID) and UserID (UID)
Purpose is to allow Other Network Download (OND) and further specific services
over dedicated portal based on AP. For such, specific DID (32 bytes) and UID (8
bytes) needs to be paired and overwritten into memory for internal client
encryption,as below.
Those
DID/UID codes can only be set using UART commands following enclosed SIACP
requirements.
LAN Test
A rough LAN test can be done by connecting Ethernet to TV’s RJ45 and check that
IP, subnet mask, DNS addresses, which are visible on HomeàSettingsàNetworkàEthernet settingsàIP settings” (ensure that “Internet
Connection” is Enabled at first). More in-depth test can be performed faster
using suitable UART/IR commands following SIACP requirements. SW will
internally manage Network ID (NID) flag controlling all MAC/DID/UID integrity
to facilitate PA screening further.
Shop init
At final process stage, it’s necessary to perform Shop init before any packing
to leave Factory mode and restore User default presets according to the
requirement of order.
This function is accessible by selecting “Factory MenuàShop”, then pressing RCU “Right ”or”
Left” key.
Other faster methods are available on above enclosed SIACP requirements.
Warm-up Test
Following TCL standard and practices, it’s required minimum 15min of Warm-Up
that can be considered as Burn-In. Additional aging for White Balance alignment
is no more necessary due to consistent picture performance with cloning usage.
This function is accessible by selecting “Factory menu àWarm up”, pressing RCU “Right” or
”Left” key to set it ON, and then it enter in Warm up mode. Press “Menu” key on
keyboard to exit the burning mode. Other faster methods are available on above
enclosed SIACP requirements.

White Balance (WB) Adjustment
The White Balance generally is customized by PQ engineer, and uploaded to the
PDM system, anyone else shouldn’t change the value in the menu. If it is
necessary to adjust, the following content can offer some reference, but the
process of adjusting White Balance is out of the range of this file. Please
refer to the relevant technical file of HuiZhou factory of TCL.
White
balance adjustment takes the Normal color temperature of HDMI channel as the
reference.
Warm and Cold tone is relative to Normal mode. The adjustable gain range is
0~255.
The Normal color temperature of other channel is relative to the Normal mode of
HDMI channel. The adjustable gain range is also 0~255.
The manual adjustment is according to the regulation above. Additionally, when
manually adjust, it needs to do White Balance in it first.
Take signal generator 22293 as an example, the timing value and pattern value
of each source.
Note:
1)
The input signal is 80% white when the pattern value of 22293 is 103.
2) The adjustment of White Balance should fulfill TCL matching specification.
